Bullet Nearby Stars (astrometric monitoring)
- None
- Evening session (3.1 hrs duration). 
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Ambient Temperature:  -3.0°C minimum
- CCD operation -30°C (at 63% average cooling).  
- main objectives of the session were to acquire images of a number of Herschel 400 objects in Ursa Major.  Secondary objective was to acquire images selected project stars for ongoing photometric and astrometric analysis.
